1'0 all whom it may concern.-

Be it known that I, DANIEL WILDE, a citizen of the United States, and a resident of Washington, in the county of Washington and State of Iowa, have invented a new and useful Improvement in Spring-Bolts for Windows, of which the following is a specification.

My invention relates to an improvement in spring-bolts for windows; and the object, primarily, is to provide means for fastening the bolt when it is desired to raise or lower the sash, thus relieving the hands which otherwise are necessary to hold the bolts when operating the sash, transom, outside window, or whatever it may be or when putting them in place, thus leaving the hands free to attend to the work.

With these objects in view my invention consists in a sliding wedge so connected with the bolt that it will hold the latter away from the frame when the wider portion of the wedge is slid against the end of the bolt.

It further consists in certain novel features of construction and combinations of parts which will be hereinafter described, and

pointed out in the claims.

In the accompanying drawin s, Figure 1 is a view showing my improvec. spring-bolt applied to a window-sash. Fig. 2 is an en larged detail, partly in section, of the improved bolt and bolt-fastener; and Fig. 3 is a modification.

A represents the bolt, and l is the usual sleeve or casing within which the bolt slides, confining the usual spiral spring 2 for actuating it, and the sleeve or casing is adapted to be mortised in the sides of the sash in the usual manner. A head3 is formed on the inner end of the bolt, between which head and.

the adjacent end of the sleeve or casing my improved fastener 6 is mounted. This fastener is wedge shape through the main por tion of its length, the inclining part preferably being on the edge next to the head of the bolt against whlch it bears, having a cam action, the opposite edge sliding against the end of the sleeve or casing. At the ends the inclining portion is preferably flattened slightly, as at 5 5, to afford an increased bearing-seat for the head when the wedge is in either of its extreme positions, thus retaining it in place.

The wedge may be variously constructed, as, for instance, of sheet metal folded in the center to form two parallel members which straddle or embrace opposite sides of the bolt with. the extreme end bent inward to close the wedge at that end whereby to prevent its removal from the bolt.

In the modification instead of using the cylindrical sleeve or casing 1, adapted to be mortised into the sash, I employ a casing having a base-flange 8 8 on each side, and when thus constructed it is capable of being applied to the surface of the sash, to the window-frame, to the meeting-rail of the lower sash, or to a door or transom. When fastened to the sash the end of the bolt would go into a hole in the side of 'the window-frame,

and when fastened to the frame the bolt would extend into a hole in the sash. In short, when thus constructed, it can be used anywhere where two flat surfaces come in line with each other or at right angles to each other. A keeper 9 may be similarly constructed and used when required.

In operation when it is desired to withdraw the bolt or bolts, instead of grasping them by the hand and pulling them inward, thus occupying both hands and preventing their being used otherwise, as heretofore, the fastening-wedge is simply slid endwise until the wider end is against the head of the bolt, thus forcing the latter backward and hold ing it in this position and leaving the hands free to be otherwise employed.

This simple attachment is cheap to manu facture, easy to apply, and it can be seen that it is most effectual in the performance of its functions.

Slight changes might be resorted to in the form and arrangement of the several parts described without departing from the spirit and scope of my invention, and hence I do not wish to limit myself to the exact construction herein set forth; but,

Having fully described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. The combination of a spring-actuated slide-bolt having a head thereon, of awedgeshaped fastener hairing pivotally-sliding connection against the head and pressing in opposite direction from the pressure exerted by the spring for controlling the position of the bolt.

2. The combination with a sleeve or casing and a spring-actuated bolt having sliding connection therein, said bolt having a head on its outerprotruding end, of a fastener having pivotal and wedging action between the IIO head and adj acent' end of the sleeve orcasi'ng for forcing the boltendwise against the action ofthe spring.

3. The combination with :a sleeve or cas- 5 ing, and a spring-actuated bolt slidable therein, one endof the bolt protruding beyond the end of the casing and having a head thereon, and a Wedge-shaped fastener straddling the bolt and having sliding connection therewith between the sleeve or'casing and the head.

4. The combination with a sleeve or casing, and aspring-actuated'bolt slidable therein, one end of the bolt protruding beyond the end of he casing and having ahead thereon, and a wedge-shaped fastener straddling the bolt and having sliding connection therewith between the sleeve or casing and the head, the fastener flattened at the ends to vaffordincreased bearing-seats for the head when the fastener is placed in either of its extreme positions.

5. The combination with a sleeve or casing and a-spring-actuated bolt sliding therein, said bolt having a head or enlargement thereon, of'a wedge-shaped fastening device mounted to slide and capable of turning on the bolt, one edge engaging the head thereon, and-theoppositezedge the adjacent end of the sleeve or casing whereby to force the bolt backward, and retain it in position.

6. The combination with a sleeve or casing and a spring-actuated bolt sliding therein, said bolt having a head or enlargement thereon, of a wedge-shaped fastening device mounted-to slide on the bolt, one edgeengaging the head thereon, and the opposite edge the adjacent end of *the sleeve or casing whereby to 'force the bolt backward, and retain it in position, the ends of the wedgeshaped fastener having bearing-seats thereon.

In testimony whereof I have signed this specification in the presence of two subscribing witnesses. I
